Description

Technical Field

[0001] This utility model relates to the field of magnetic flux disk motor rotor technology, and in particular to an axial magnetic flux disk motor rotor structure. Background Technology

[0002] The motor rotor is a rotating component in an electric motor. It is usually composed of copper coils and an iron core, or a slow-moving rotor composed of aluminum conductors and copper fans, or a skeleton rotor composed of fine wires. In a DC motor, current passes through the coils to form a magnetic field, which drives the rotor to rotate. In an AC motor, the changing magnetic field generates an electric force, which drives the rotor to rotate.

[0003] The existing motor rotor disc is made entirely of thin metal, which can effectively improve the stability of the motor rotor during operation. However, because the motor rotor disc is thin and light, it will rust and weather after long-term use, resulting in holes and loosening. This will not only reduce the operating stability of the motor rotor, but also increase the operating burden on the motor rotor.

[0004] To address this, we designed an axial flux disk type motor rotor structure. Utility Model Content

[0005] The purpose of this invention is to propose an axial flux disk type motor rotor structure to solve the problem of thin and light structure in existing technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An axial flux disc type motor rotor structure includes a disc body, on which a plurality of permanent magnets are provided, and the sidewall of the disc body is provided with a rubber surface for reducing scratches;

[0008] The disk body is provided with multiple mounting blocks for fixing permanent magnets, multiple second extension plates for improving stability, and multiple anti-slip textures.

[0009] Preferably, the mounting block is fixed to the disc body by fasteners, and the mounting block is arranged in a ring shape on the disc body.

[0010] Preferably, the mounting block is symmetrically provided with clamping blocks for limiting the permanent magnet, and the inner wall of the clamping block abuts against the permanent magnet.

[0011] Preferably, the disc body is provided with a plurality of flip shafts, and the flip shafts are fixedly connected to the disc body by fasteners. The flip shafts are provided with a first extension plate, and the second extension plate is fixedly connected to the flip shafts by fasteners. The first extension plate is provided with fixing bolts for fixing.

[0012] Preferably, the mounting block has a groove, a balancing block for improving stability is provided in the groove, and a plurality of support columns for fixing the balancing block are provided in the groove.

[0013] Preferably, the anti-slip texture is formed in a ring shape on the bottom of the disc.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. By setting the first extension plate and the second extension plate, the overall operational stability of the disc body can be improved during operation. At the same time, the second extension plate can increase the thickness of one side of the disc body. Compared with the prior art, it can increase the thickness of one side of the disc body, reduce the occurrence of thin structures, and thus improve the efficiency of the disc body during operation and reduce the operational burden.

[0016] 2. By setting up the placement block and the clamping block, this utility model can effectively increase the stability of the permanent magnet during the installation process. At the same time, the clamping block can reduce the permanent magnet from falling off during the operation of the disc, further improving the stability of the disc during operation.

[0022] Reference Figures 1-4An axial flux disc type motor rotor structure includes a disc body 1, which is made of aluminum alloy as in the prior art. Compared with the prior art, the disc body 1 is thicker overall, which can effectively improve stability during the covering process and reduce the burden during operation. The permanent magnet 2 is a magnet that can maintain its magnetism for a long time in the prior art, called a permanent magnet. The rubber surface is set on the outer side of the disc body 1 and extends along the inner edge of the side wall of the disc body 1 to the top, which can effectively reduce the phenomenon of the disc body 1 falling off during operation, thereby increasing the overall friction.

[0023] The disk body 1 is provided with multiple mounting blocks 3 for fixing permanent magnets 2. The mounting blocks 3 are made of metal that does not affect the magnetic field in the existing technology, so as to avoid the different magnetic fields affecting the use of permanent magnets 2. The mounting blocks 3 are fixed to the disk body 1 by fasteners. The fasteners are auxiliary connecting components in the existing technology, which improve the connection strength between the two and facilitate disassembly and maintenance in the future. The mounting blocks 3 are arranged in a ring on the disk body 1. There are a total of ten mounting blocks 3. The specific number can be customized according to the number of permanent magnets 2.

[0024] The mounting block 3 is symmetrically provided with clamping blocks 4 for limiting the permanent magnet 2. The clamping blocks 4 are made of aluminum alloy in the prior art. Their main purpose is to ensure that the permanent magnet 2 is always kept in a tight state on the mounting block 3, so as to prevent the disk 1 from falling off during operation. The inner wall of the clamping block 4 abuts against the permanent magnet 2. The two sides of the clamping block 4 are fixedly connected to the mounting block 3 by welding, thereby ensuring the stability of the permanent magnet 2 on the mounting block 3.

[0025] The disc body 1 is provided with multiple second extension plates 8 for improving stability. The second extension plates 8 are used to increase the thickness of one side of the disc body 1 and the overall stability during operation. The disc body 1 is provided with multiple flip shafts 5. The flip shafts 5 are existing technology, with one half embedded in the disc body 1 and the other half exposed on the disc body 1. The flip shafts 5 are fixed around the disc body 1 by fasteners, which increases the overall stability and service life. The flip shafts 5 are fixedly connected to the disc body 1 by fasteners. The fasteners are existing auxiliary connecting components, which improve the connection strength between the two and facilitate disassembly and maintenance in the future. The flip shafts 5 are provided with first extension plates 6. The first extension plates 6 are extensions of the second extension plates 8, which are used to increase the thickness of the surface of the disc body 1 and improve operational stability. The second extension plates 8 are fixedly connected to the flip shafts 5 by fasteners. The fasteners are existing auxiliary connecting components, which improve the connection strength between the two and facilitate disassembly and maintenance in the future. The first extension plates 6 are provided with fixing bolts 7 for fixing. The fixing bolts 7 are existing technology, which are used to fix one end of the first extension plates 6 to reduce the phenomenon of falling off.

[0026] The mounting block 3 has a groove inside it for arranging the balance block 9 below. The ventilation effect of the groove can improve the stability of the disc 1. The balance block 9 is made of steel and is used to increase the stability of the mounting block 3 on the disc 1. Multiple support columns 10 are provided in the groove to fix the balance block 9. The support columns 10 are auxiliary components.

[0027] Multiple anti-slip patterns 11 are provided on the disc body 1. The anti-slip patterns 11 are auxiliary structures. The anti-slip patterns 11 are arranged in a ring at the bottom of the disc body 1, which can improve the contact effect at the bottom of the disc body 1 and improve the overall friction.

[0028] The working principle of this utility model is as follows:

[0029] The disk body 1 is made of aluminum alloy and is thicker than traditional designs, which helps maintain stability during the covering process and reduces the burden during operation. The permanent magnets 2, which maintain their magnetism over a long period, are placed in mounting blocks 3 on the disk body 1. The mounting blocks 3 are made of a metal material that does not affect the magnetic field and are fixed to the disk body 1 with fasteners for easy disassembly and maintenance. Each mounting block 3 has symmetrically arranged clamping blocks 4, which are welded to the mounting blocks 3 to ensure that the permanent magnets 2 remain firmly in contact, preventing them from falling off during operation. The disk body 1 has multiple second extension plates 8 to increase the thickness on one side and improve overall operational stability. The disk body 1 also has a flip shaft 5, half of which is embedded inside the disk body 1, and the other half is exposed. The flip shaft 5 is fixed around its perimeter with fasteners, increasing overall stability and service life. The first extension plate 6 on the flip shaft 5 serves as an extension of the second extension plate 8, further increasing the surface thickness of the disk body 1 and operational stability. The mounting blocks 3 have grooves inside, in which balance blocks 9, made of steel, are arranged to increase stability. Multiple support columns 10 are also provided in the groove as auxiliary components to further fix the balance block 9. The bottom of the disc 1 is provided with annular anti-slip texture 11, which is an auxiliary structure that only improves the contact effect and overall friction of the bottom of the disc 1.
